If you look at Spidream in relation to the rest of your sprites, you'll see that it'll look like it's standing on its mandibles. I can see that sprite working on a tile for a puzzle but you'd have to figure out what that puzzle would be and where it would be.

I think it looks pretty cool, but it might be difficult to recognize for someone who isn't quite as familiar with Topaz Pokemon. I could see it as some kind of puzzle element, perhaps in a Khaphix-related subplot.
